That would take some real getting used to lol so much for their “Little Cat”
And then we follow Jaime who is trying to guess where is Brynden all along, he also thinks that probably he joined the brotherhood, or probably he might try to free Edmure or...what else. But from all possibilities Jaime did eliminate Castle black from Brynden words.
I might be wrong, but I don't believe Brynden goes against Robb last wish, i think he played Jaime pretty well. About Robb letter, i think Robb did legitimate Jon but he didn't eliminate other possibilities. "We know no king but the King in the North whose name is Stark "might be the exactly Robb' words. Remember Cat was suggesting someone from another branch like Royce cousin or some shit like this. Or it will be Jon or sansa when she get divorce from Lannister, or Rickon if he is still alive, or Jeyne if she is pregnant but no one else except a Stark.
I love this theory. I have been wondering and waiting for anyone to bring up the fact that he named Jon Snow his heir. There have to have been several people that knew bc he had all his lords sign it. Commanded them to. I know most of them died at the Red Weddinf but a few lived to be ransomed at the very least. I hadn’t thought of Edmure being the one to tell him to find Jon snow. Now, if he does end up meeting with Lady Stoneheart, how do you think it goes when he tells her what he’s on his way to do?
